Selection genius

Alright. When you are doing a complex selection, let's say with the lasso tool, and you forget where you started the selection, like you can't find it too easily anymore, I hate when this happens :-), is there some way to get the beginning point to say HERE I AM without making insane scribbles everywhere until you get the closing circle.

Actually, this would work. However, it would be a nice enhancement if the selection tool itself had a way of helping to resolv this problem. Maybe the starting pt good be a different tint or a keyboard short cut could highlight it. I guess I was hoping that this feature was already there and I just didn't know it.
